Yesterday,
During Installation of Oracle database 9i base on RHEL 4 ES,
I got Found error occurred when create the database using dbca,
and it keeps failing at the same point (Creating data dictionary Views)
This the error number Detail "ORA 29807 - specified operator does not exist"
Workaround;
just ignore the error and DBCA proceeds normally. Once the database is ready,
login as SYS and run this script manually:
$ORACLE_HOME/rdbms/admin/prvtxml.plb
SQL> @?/rdbms/admin/prvtxml.plb
